Each of the three current feedback amplifiers has 5 ma of output current, and is optimized for driving one back-terminated video load (15 Ω).

This makes the AD813 ideal for broadcast and consumer video electronics. The AD813 offers low power of 5.5 ma per amplifier max and runs on a single +3 V power supply. The outputs of each amplifier swing to within one volt of either supply rail to easily accommodate video signals. While operating on a single +5 V supply the AD813 still achieves.1 db flatness to 2 MHz and.5% &.5 of differential gain and phase performance. All this is offered in a small 14-lead plastic DIP or SOIC package. These features make this triple amplifier ideal for portable and battery powered applications where size and power are critical. The outstanding bandwidth of 125 MHz along with 5 V/µs of slew rate make the AD813 useful in many general purpose, high speed applications where a single +3 V or dual power supplies up to ±15 V are needed. Furthermore the AD813 contains a high speed disable function for each amplifier in order to power down the amplifier or high impedance the output. This can then be used in video multiplexing applications. The AD813 is available in the industrial temperature range of 4 C to +85 C in plastic DIP and SOIC packages as well as chips % 5mV 5ns Figure 2.

6 Maximum Power Dissipation The maximum power that can be safely dissipated by the AD813 is limited by the associated rise in junction temperature. The maximum safe junction temperature for the plastic encapsulated parts is determined by the glass transition temperature of the plastic, about 15 C. Exceeding this limit temporarily may cause a shift in parametric performance due to a change in the stresses exerted on the die by the package. Exceeding a junction temperature of 175 C for an extended period can result in device failure. While the AD813 is internally short circuit protected, this may not be enough to guarantee that the maximum junction temperature (15 C) is not exceeded under all conditions. To ensure proper operation, it is important to observe the derating curves. It must also be noted that in (noninverting) gain configurations (with low values of gain resistor), a high level of input overdrive can result in a large input error current, which may result in a significant power dissipation in the input stage. This power must be included when computing the junction temperature rise due to total internal power.

13 General Consideration The AD813 is a wide bandwidth, triple video amplifier that offers a high level of performance on less than 5.5 ma per amplifier of quiescent supply current. With its fast acting power down switch, it is designed to offer outstanding functionality and performance at closed-loop inverting or noninverting gains of one or greater. Built on a low cost, complementary bipolar process, and achieving bandwidth in excess of 1 MHz, differential gain and phase errors of better than.1% and.1 (into 15 Ω), and output current greater than 4 ma, the AD813 is an exceptionally efficient video amplifier. Using a conventional current feedback architecture, its high performance is achieved through careful attention to design details. Choice of Feedback & Gain Resistors Because it is a current feedback amplifier, the closed-loop bandwidth of the AD813 depends on the value of the feedback resistor. The bandwidth also depends on the supply voltage. In addition, attenuation of the open-loop response when driving load resistors less than about 25 Ω will also affect the bandwidth. Table I contains data showing typical bandwidths at different supply voltages for some useful closed-loop gains when driving a load of 15 Ω. (Bandwidths will be about 2% greater for load resistances above a few hundred ohms.) Table I. 3 db Bandwidth vs. Closed-Loop Gain and Feedback Resistor, (R L = 15 ) V S (V) Gain R F ( ) BW (MHz) ± ± To estimate the 3 db bandwidth for closed-loop gains or feedback resistors not listed in the above table, the following two pole model for the AD813 may be used: A CL = ( S R + Gr ) C 2 2π f F IN T 2 G + S ( R + Gr ) C + 1 F IN T where: A CL = closed-loop gain from transcapacitance G = 1 + R F /R G r IN = input resistance of the inverting input C T = transcapacitance, which forms the open-loop dominant pole with the transresistance R F = feedback resistor R G = gain resistor f 2 = frequency of second (nondominant) pole s = 2 πj f Appropriate values for the model parameters at different supply voltages are listed in Table II. Reasonable approximations for these values at supply voltages not found in the table can be obtained by a simple linear interpolation between those tabulated values which bracket the desired condition. Table II. Two Pole Model Parameters at Various Supplies V S (V) r IN ( ) C T (pf) f 2 (MHz) ± ± As discussed in many amplifier and electronics textbooks (such as Roberge s Operational Amplifiers: Theory and Practice), the 3 db bandwidth for the 2-pole model can be obtained as: f 3 = f n [ 1 2d 2 + (2 4d 2 +4d 4 ) 1/2 ] 1/2 where: 1/2 f f n = 2 (R F + Gr IN ) C T and: d = 1 [ 2 f 2 (R F +Gr IN ) C T ] 1/2 This model will predict 3 db bandwidth within about 1% to 15% of the correct value when the load is 15 Ω. However, it is not accurate enough to predict either the phase behavior or the frequency response peaking of the AD813. The choice of feedback resistor is not critical unless it is important to maintain the widest, flattest frequency response. The resistors recommended in the table are those (metal film values) that will result in the widest.1 db bandwidth. In those applications where the best control of the bandwidth is desired, 1% metal film resistors are adequate. Wider bandwidths can be attained by reducing the magnitude of the feedback resistor (at the expense of increased peaking), while peaking can be reduced by increasing the magnitude of the feedback resistor. 13

14 Printed Circuit Board Layout Guidelines As with all wideband amplifiers, printed circuit board parasitics can affect the overall closed-loop performance. Most important for controlling the.1 db bandwidth are stray capacitances at the output and inverting input nodes. Increasing the space between signal lines and ground plane will minimize the coupling. Also, signal lines connecting the feedback and gain resistors should be kept short enough that their associated inductance does not cause high frequency gain errors. Power Supply Bypassing Adequate power supply bypassing can be very important when optimizing the performance of high speed circuits. Inductance in the supply leads can (for example) contribute to resonant circuits that produce peaking in the amplifier s response. In addition, if large current transients must be delivered to a load, then large (greater than 1 µf) bypass capacitors are required to produce the best settling time and lowest distortion. Although.1 µf capacitors may be adequate in some applications, more elaborate bypassing is required in other cases. When multiple bypass capacitors are connected in parallel, it is important to be sure that the capacitors themselves do not form resonant circuits. A small (say 5 Ω) resistor may be required in series with one of the capacitors to minimize this possibility. As discussed below, power supply bypassing can have a significant impact on crosstalk performance. Achieving Low Crosstalk Measured crosstalk from the output of Amplifier 2 to the input of Amplifier 1 of the AD813 is shown in Figure 4. All other crosstalk combinations, (from the output of one amplifier to the input of another), are a few db better than this due to the additional distance between critical signal nodes. 1 2 R L = 15 A carefully laid-out PC board should be able to achieve the level of crosstalk shown in the figure. The most significant contributors to difficulty in achieving low crosstalk are inadequate power supply bypassing, overlapped input and/or output signal paths, and capacitive coupling between critical nodes. The bypass capacitors must be connected to the ground plane at a point close to and between the ground reference points for the loads. (The bypass of the negative power supply is particularly important in this regard.) This requires careful planning as there are three amplifiers in the package, and low impedance signal return paths must be provided for each load. (Using a parallel combination of 1 µf,.1 µf, and.1 µf bypass capacitors will help to achieve optimal crosstalk.) The input and output signal return paths (to the bypass caps) must also be kept from overlapping. Since ground connections are not of perfectly zero impedance, current in one ground return path can produce a voltage drop in another ground return path if they are allowed to overlap. Electric field coupling external to (and across) the package can be reduced by arranging for a narrow strip of ground plane to be run between the pins (parallel to the pin rows). Doing this on both sides of the board can reduce the high frequency crosstalk by about 5 db or 6 db. Driving Capacitive Loads When used with the appropriate output series resistor, any load capacitance can be driven without peaking or oscillation. In most cases, less than 5 Ω is all that is needed to achieve an extremely flat frequency response. As illustrated in Figure 44, the AD813 can be very attractive for driving large capacitive loads. In this case, the AD813 s high output short circuit current allows for a 15 V/µs slew rate when driving a 51 pf capacitor. R F 3 4 +V S.1 F CROSSTALK db R G RT 1.

15 CLOSED-LOOP GAIN db R S = 3 R S = 5 R S = V S = R F = R L = 1k C L = 1pF Overload Recovery There are three important overload conditions to consider. They are due to: input common-mode voltage overdrive, output voltage overdrive, and input current overdrive. When the amplifier is configured for low closed-loop gains, and the input common-mode voltage range is exceeded, the recovery time will be very fast, typically under 3 ns. When configured for a higher gain, and overloaded at the output, the recovery time will also be short. For example, in a gain of +1, with 6 db of input overdrive, the recovery time of the AD813 is about 25 ns (see Figure 45) V 5ns Figure 42. Response to a Small Load Capacitor at V S = ±5 V 9 R F = R L = 1k 1 % 2V CLOSED-LOOP GAIN db C L = 51pF, R S = 15 C L = 15pF, R S = Figure 43. Response to a Large Load Capacitor at V S = ±15 V Figure db Overload Recovery, G = +1, (R L = 5 Ω, R F = 357 Ω, V S = ±5 V) In the case of high gains with very high levels of input overdrive, a longer recovery time will occur. For example, if the input common-mode voltage range is exceeded in the gain of +1, the recovery time will be on the order of 1 ns. This is primarily due to current overloading of the input stage. As noted in the warning under Maximum Power Dissipation, a high level of input overdrive in a high noninverting gain circuit can result in a large current flow in the input stage. Though this current is internally limited to about 4 ma, its effect on the total power dissipation may be significant. 1ns % Figure 44.

16 High Performance Video Line Driver At a gain of +2, the AD813 makes an excellent driver for a back terminated 75 Ω video line. Low differential gain and phase errors and wide.1 db bandwidth can be realized over a wide range of power supply voltage.

17 Operation Using a Single Supply The AD813 will operate with total supply voltages from 36 V down to 2.4 V. With proper biasing (see Figure 52) it can make an outstanding single supply video amplifier. Since the input and output voltage ranges extend to within 1 V of the supply rails, it will handle a 1.3 V peak-to-peak signal on a single 3.3 V supply, or a 3 V peak-to-peak signal on a single 5 V supply. The small signal.1 db bandwidths will exceed 1 MHz in either case, and the large signal bandwidths will exceed 6 MHz. The capacitively coupled cable driver in Figure 52 will achieve outstanding differential gain and phase errors of.5% and.5 degrees respectively on a single 5 V supply. Resistor R2, in this circuit, is selected to optimize the differential gain and phase by biasing the amplifier in its most linear region.

Biasing for Single Supply Operation GAIN PHASE V S = R F = 619 R L = PHASE SHIFT Degrees Disable Mode Operation Pulling the voltage on any one of the Disable pins about 2.5 V down from the positive supply will put the corresponding amplifier into a disabled, powered down, state. In this condition, the amplifier s quiescent supply current drops to about.5 ma, its output becomes a high impedance, and there is a high level of isolation from input to output. In the case of the gain of two line driver for example, the impedance at the output node will be about the same as for a 1.4 kω resistor (the feedback plus gain resistors) in parallel with a 12.5 pf capacitor and the input to output isolation will be about 65 db at 1 MHz. Leaving the Disable pin disconnected (floating) will leave the corresponding amplifier operational, in the enabled state. The input impedance of the disable pins is about 35 kω in parallel with a few pf. When grounded, about 5 µa flows out of a disable pin on ±5 V supplies. Input voltages greater than about 1.5 V peak-to-peak will defeat the isolation. In addition, large signals (greater than 3 V peakto-peak) applied to the output node will cause the output impedance to drop significantly. When the Disable pins are driven by complementary output CMOS logic (such as the 74HC4), the disable time is about 8 ns (until the output goes high impedance) and the enable time is about 1 ns (to low impedance output) on ±15 V supplies. When operated on ±15 V supplies, the disable pins should be driven by open drain logic. In this case, pull-up resistors from the disable pins to the plus supply will ensure minimum switching time SELECT Figure 53.

18 3:1 Video Multiplexer Wiring the amplifier outputs together will form a 3:1 mux with outstanding gain flatness. Figure 55 shows a recommended configuration which results in.1 db bandwidth of 2 MHz and OFF channel isolation of 6 db at 1 MHz on ±5 V supplies. The time to switch between channels is about 18 ns. Switching time is only slightly affected by signal level. 5mV 5ns Single Supply Differential Line Driver Due to its outstanding overall performance on low supply voltages, the AD813 makes possible exceptional differential transmission on very low power. The circuit of Figure 59 will convert a single-ended, ground referenced signal to a differential signal whose common-mode reference is set to one half the supply voltage. This allows for a greater than 2 V peak-to-peak signal swing on a single 3 V power supply. A bandwidth over 3 MHz is achieved with 2 ma of output drive on only 3 mw of quiescent power (excluding load current) V OUT + 1 F + R L % Figure 56.
